2012-02-03qdev: refactor device creation to allow bus_info to be set only in classAnthony Liguori1-23/+19
As we use class_init to set class members, DeviceInfo no longer holds this information. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qdev: allow classes to overload qdev functionsAnthony Liguori1-20/+33
This allows us to drop per-Device registration functions by allowing the class_init functions to overload qdev methods. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qdev: remove info from classAnthony Liguori3-44/+80
Now DeviceInfo is no longer used after object construction. All of the relevant members have been moved to DeviceClass. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03qdev: make DeviceInfo privateAnthony Liguori4-23/+48
Introduce accessors and remove any code that directly accesses DeviceInfo members. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03usb: separate out legacy usb registration from type registrationAnthony Liguori11-25/+37
Type registeration is going to get turned into a QOM call so decouple the legacy support. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-03usb-hid: simplify class initialization a bitAnthony Liguori1-14/+13
We can probably model USBHidDevice as a base class to get even better code sharing but for now, just use a common function to initialize the common class members. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-01hw/vmmouse.c: Disable vmmouse after rebootGerhard Wiesinger1-0/+2
Bugfix after reboot when vmmouse was enabled and another OS which uses e.g. PS/2 mouse. Details: When a guest activated the vmmouse followed by a reboot the vmmouse was still enabled and the PS/2 mouse was therefore unsusable. When another guest is then booted without vmmouse support (e.g. PS/2 mouse) the mouse is not working. Reason is that VMMouse has priority and disables all other mouse entities and therefore must be disabled on reset. Testscenario: 1.) Boot e.g. OS with VMMouse support (e.g. Windows with VMMouse tools) 2.) reboot 3.) Boot e.g. OS without VMMouse support (e.g. DOS) => PS/2 mouse doesn't work any more. Fixes that issue. Testscenario 2 by Jan Kiszka <jan.kiszka@siemens.com>: Confirm that this patch fixes a real issue. Setup: qemu.git, opensuse 11.4 guest, SDL graphic, system_reset while guest is using the vmmouse. Without the patch, the vmmouse become unusable after the reboot. Also, the mouse stays in absolute mode even before X starts again. Fixed by: Disabling the vmmouse in its reset handler.

2012-02-01mc146818rtc: Use lost_tick_policy propertyJan Kiszka1-7/+19
Allow to configure the MC146818 RTC via the new lost tick policy property and replace rtc_td_hack with this mechanism. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-01qdev: Introduce lost tick policy propertyJan Kiszka2-0/+62
Potentially tick-generating timer devices will gain a common property: lock_tick_policy. It allows to encode 4 different ways how to deal with tick events the guest did not process in time: discard - ignore lost ticks (e.g. if the guest compensates for them already) delay - replay all lost ticks in a row once the guest accepts them again merge - if multiple ticks are lost, all of them are merged into one which is replayed once the guest accepts it again slew - lost ticks are gradually replayed at a higher frequency than the original tick Not all timer device will need to support all modes. However, all need to accept the configuration via this common property. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-30m48t59: use rtc_clock for alarm timerPaolo Bonzini1-2/+2
This lets the RTC get adjustments from the host NTP client. The watchdog still uses the vm_clock. The previous behavior is available with "-rtc clock=vm".

2012-01-27qdev: prepare source tree for code conversionAnthony Liguori15-312/+304
These are various small stylistic changes which help make things more consistent such that the automated conversion script can be simpler. It's not necessary to agree or disagree with these style changes because all of this code is going to be rewritten by the patch monkey script anyway.

2012-01-27qdev: add class_init to DeviceInfoAnthony Liguori2-0/+9
Since we are still dynamically creating TypeInfo, we need to chain the class_init function in order to be able to make use of it within subclasses of TYPE_DEVICE. This will disappear once we register TypeInfos directly. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-01-27qdev: add a interface to register subclassesAnthony Liguori2-2/+8

2012-01-26scsi: Guard against buflen exceeding req->cmd.xfer in scsi_disk_emulate_commandThomas Higdon1-9/+1
Limit the return value (corresponding to the length of the buffer to be DMAed back to the intiator) to the value in req->cmd.xfer, which is the amount of data that the initiator expects. Eliminate now-duplicate code that does this guarding in the functions for individual commands. Without this, the SCRIPTS code in the emulated LSI device eventually raises a DMA interrupt for a data overrun when an INQUIRY command whose buflen exceeds req->cmd.xfer is processed. It's the responsibility of the client to provide a request buffer and allocation length that are large enough for the result of the command.
